The measure of angle D in the inscribed triangle is as follows;
∠D = 63 degrees
How to solve circle theorem?The circle theorem can be use to find the ∠D as follows;
The triangle BCD is inscribed in the circle.
Using circle theorem,
The angle of each triangle is double the angle of the arc it create.
Therefore,
arc BC = m∠D
m∠B = 134 / 2 = 67 degrees.
Therefore, using sum of angles in a triangle.
67 + 50 + m∠D = 180
m∠D = 180 - 50 - 67
m∠D = 63 degrees.

Simplify the expression 3(x + 2)(x2 − x − 8). (6 points)
Answer:
3x³ + 3x² - 30x - 48
Step-by-step explanation:
3(x + 2)(x² - x - 8) ← distribute (x + 2) by 3
= (3x + 6)(x² - x - 8)
each term in the second factor is multiplied by each term in the first factor
= 3x(x² - x - 8) + 6(x² - x - 8) ← distribute both parenthesis
= 3x³ - 3x² - 24x + 6x² - 6x - 48 ← collect like terms
= 3x³ + 3x² - 30x - 48

Use the distributive property with factoring to find the equivalent expression. 20a + 28b = ( a + 7b)
The equivalent expression after factoring 20a + 28b = ( a + 7b) using the distributive property is 19a + 21b = 0.
What is Distributive Property?According to the distributive property, an expression in the form A (B + C) can be solved as A (B + C) = AB + AC. This distributive law applies to subtraction as well and is written as A (B - C) = AB - AC. This means that operand A is shared by the other two operands.
The given equation is 20a + 28b = ( a + 7b).
20a + 28b = ( a + 7b).
Now, subtract both sides by a.
20a - a + 28b = a + 7b - a.
19a + 28b = 7b.
Now, subtracting both sides by 7b.
19a + 28b - 7b = 7b - 7b.
19a + 21b = 0.
Therefore, the equivalent expression to 20a + 28b = ( a + 7b) is 19a + 21b = 0.
use the formulas for lowering powers to rewrite the expression in terms of the first power of cosine cos^4
The expression cos⁴ θ in terms of the first power of cosine is [ 3 + 2cos 2θ + cos 4θ]/8.
The power-reducing formula, for cosine, is,
cos² θ = (1/2)[1 + cos 2θ].
In the question, we are asked to use the formulas for lowering powers to rewrite the expression in terms of the first power of cosine cos⁴ θ.
We can do it as follows:
cos⁴ θ
= (cos² θ)²
= {(1/2)[1 + cos 2θ]}²
= (1/4)[1 + cos 2θ]²
= (1/4)(1 + 2cos 2θ + cos² 2θ] {Using (a + b)² = a² + 2ab + b²}
= 1/4 + (1/2)cos 2θ + (1/4)(cos ² 2θ)
= 1/4 + (1/2)cos 2θ + (1/4)(1/2)[1 + cos 4θ]
= 1/4 + cos 2θ/4 + 1/8 + cos 4θ/8
= 3/8 + cos 2θ/4 + cos 4θ/8
= [ 3 + 2cos 2θ + cos 4θ]/8.
Thus, the expression cos⁴ θ in terms of the first power of cosine is [ 3 + 2cos 2θ + cos 4θ]/8.

Using the tangent ratio
Tan θ = opposite/adjacent
Let's substitute the value of theta, opposite and adjacent

O 0.0059
O 0.001
Answer: 0.0059 (choice C)
Explanation:
There are 4 jacks out of 52 cards total.
4/52 = 1/13 is the probability of getting a jack.
The same applies to an ace as well.
The probability of a jack followed by an ace is (1/13)*(1/13) = 0.0059 approximately, when we replace the first card. If the replacement wasn't done, then the second probability would be different from 1/13.

Answer:
A
Step-by-step explanation:
Area of the rectangle is 15*20=300
Area of the triangle is 8*17/2=68
Total area is 300+68=368
Perimeter is 15+20+20+8+17=80
Answer:
[tex]\rm {P = 80 \space\ feet,\space\ A = 360 \space\ square \space\ feet}[/tex]
Step-by-step explanation:
The perimeter of a shape is the sum of all the sides of the shape.
• Perimeter of the polygon = 15 + 20 + 17 + 8 + 20
= 80 feet
To find the area of the polygon, we can separately find the areas of the triangle and the rectangle and then add them together.
• Area of rectangle = length × breadth
= 15 × 20
= 300 square feet
• Area of triangle = [tex]\frac{1}{2}[/tex] × base × height
As the height of the triangle is not provided, we have to calculate it.
Let the height of triangle = [tex]x[/tex]
Using Pythagoras's theorem:
[tex]x^2 + 8^2 = 17^2[/tex]
⇒ [tex]x^2 = 17^2 - 8^2[/tex]
⇒ [tex]x = \sqrt{17^2 - 8^2}[/tex]
⇒ [tex]x=\bf15[/tex]
Now using this value of height, we can find the area of the triangle:
Area of triangle = [tex]\frac{1}{2}[/tex] × 8 × 15
= 60 square feet
• Finally, we can add the areas of the triangle and rectangle together to find the area of the polygon:
Area of polygon = 300 + 60
= 360 square feet

Therefore, since a and the unmarked angle are congruent since it is an isosceles triangle, we subtract 40 from 180, with a result of 140. With 140, we divide by 2 to find the degrees for both the unmarked angle and angle a, since they are congruent. 140/2 = 70, Angle A will equal to 70 degrees

Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously?
f(n + 1) = f(n) + 1.5
f(n + 1) = f(n) + 0.75
f(n + 1) = one-halff(n)
f(n + 1) = three-halvesf(n)
The recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously is f(n + 1) = f(n) + 0.75
Recursive functionsThe general recursive function is expressed as:
an+1 = d + an
where
r is the common difference
Given the sequence below

f(n + 1) = f(n) + d
f(n + 1) = f(n) + 0.75
